Porsche is introducing the 2013 Cayenne with a turbo-diesel V6 option, which will be the automaker's first diesel entry in the United States.

The 2013 Porsche Cayenne Diesel will feature a 3.0-liter V6 turbo diesel engine capable of 240 HP and 406 lb.-ft. of torque, which shoots the SUV from 0-60 in 7.2 seconds and allows a top track speed of 135 mph.

The new diesel SUV will also have an estimated fuel economy rating of 20 mpg city and 28 mpg highway, or 23 combined, according to Porsche. Also, the Cayenne Diesel can go 740 miles on a single tank of fuel.

"Highlights of the 3.0-liter V6 diesel engine in the Cayenne Diesel include high pressure common rail fuel injection and a variable vane geometry turbocharger, which give the engine improved response to driver inputs and enhanced fuel economy when compared to more conventional diesel engine technologies," said Porsche. "In addition, the engine block is constructed from compacted graphite iron (CGI), which has many of the strength properties of a conventional iron block but with a significant reduction in mass, approximately 55 lbs. (25 kilograms)."

The 2013 Porsche Cayenne Diesel will also include Porsche Traction Management (PTM) with a permanent all-wheel drive system; selective catalytic reduction (SCR) technology made of an AdBlue tank, the tank's heating system and lines to carry the AdBlue; a mechanical safeguard to protect the driver from using the wrong fuel; Diesel badges behind the front wheel wells, and an 8-speed Tiptronic S transmission.
